About Disconnector Analyzers

Disconnector analyzers may have a large number of features and applications, but the most important one is the ability to measure the current, voltage and power of a specific motor drive. The usage and the diagnosis advantages of an analyzer can improve the operations and extend the life of the electrical motor.

Another parameter to be observed and monitored, in order to evaluate the state of the disconnecting motor drive, is the operating time. For this key parameter, the ability to start the measurement by using a certain external trigger comes in hand.

These important parameters can all be monitored by using an extremely lightweight and battery-powered handheld instrument.

Handheld Disconnector Analyzers DIS-H

Handheld disconnector analyzer DIS-H is a digital instrument for measuring electrical power and the operating time of a disconnecting motor drive. It is specially designed for testing of disconnectors that are operated by an electric motor drive.

The DC current flowing through the motor is measured by a DC Current Clamp which provides the recordings of the motor current waveform, whereas the DC Voltage is obtained by using sense cables and it provides the accurate measurement of the disconnecting motor drive DC Voltage supply. The recording will be initiated at the moment on which the motor begins with closing or opening a certain disconnector, due to the fact that the motor measurement is triggered with the occurrence of current at the moment when the disconnector is being operated.

Due to the large 5.7” colored touch-screen display, test results are visible in dark places as well as under bright sunlight. Furthermore, the intuitive display can present numerical and graphical results within its layout. This feature enables quick onsite analysis of potential defects of the motor drive.

DIS-H is powered by an internal Li-ion battery that can last up to 8 hours of testing without the need for recharging.

The user can save the test results to a USB and open the results on the PC by using the DV-Win software for a more detailed analysis.
